Once formed these highly respondive radicals can start a chain reaction, standardized dominoes. Their chief danger comes from the damage they can do when they react with important cellular components such as DNA, or the cell membrane. Cells may function poorly or die if this occurs. To hold deliver radical damage the body has a defence reaction system of antioxidants.
Antioxidants are molecules which can safely interact with free radicals and terminate the chain reaction before vital molecules are damaged. Although there are several enzyme systems within the body that scavenge free radicals, the principle micronutrient (vitamin) antioxidants are vitamin E, beta-carotene, and vitamin C. Additionally, selenium, a trace metallic element that is required for proper function of one of the bodys antioxidant enzyme systems, is sometimes include in this category. The body cannot manufacture these micronutrients so they must be supplied in the diet.
